BED-RISER FOR WOVEN-WIRE MATTRESSES- Specification of Letters Patent.

Patented June 11, 1907.

Application filed April 10,1907. Serial No. 867.329.

To all whom it may concern.-

Be it known that we, JAMES M. HOLLAND and FRANKLIN HOLLAND, citizens of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Bed-Risers for Wovenire Mattresses, of which the following is a specification.

This invention relates to an improved bed riser for supporting woven-wire mattresses.

Bed risers of this class support the mattresses at its corners, being coupled to the tubes employed at each side of the mattress; two risers are at each end of the mattress and serve to support the angle-iron cross-bar to which the woven wire mattress is secured. Each riser has a laterally-projecting prong, which in practice rests on the side bar of the bedstead.

The invention has for its object to provide an improved wrought iron or steel bed riser made of one blank piece of metal to insure an article possessing strength and capable of production at low cost.

Referring to the drawing, Figure 1 is a top plan view of one corner of a bed-stead and woven-wire mattress to which a riser is secured. Fig. 2 is also a top view of one corner of a bed-stead and shows the riser in section on the line 22 of Fig. 3, and coupled to one of the tubes. Fig. 3 is an elevation or side view of one corner of the bed-stead, and shows the riser in position. Fig. 4 is a front elevation of the bed-riser and cross-bar, and shows the parts in position on the bed-stead. Fig. 5 is a perspective view of one of the bed risers shown separately.

The letter, A, designates one of the side tubes or stretchers of an ordinary wovenwire mattress-frame; and, B, designates one of the angle-iron cross-bars of which two are used with these mattressesone at the head end and the other at the foot-end. The letter, F, designates the side rail of the bedstead and, F, the corner post ofthe bed- I stead.

The riser, shown separately in Fig. 5, consists of a single piece of sheet metal having an upright flat plate, D, provided at the bottom edge and at one end with a flange, e; an

angle-shape brace, G, is attached to the front side of the upright fiat plate, D, and extends from the bottom of the latter upward to the top edge where it is secured by rivets, h. The lowermost part of this angle-pl ate at the bend, q, projects downward and below the said bottom flange, e, and thereby forms a down-projecting shoulder, 01, adjacent the said flange. As stated the brace, G, is simply a flat piece of sheetmetal having a horizontal bend, j, midway of its vertical ends-said bend forming the brace into a substantially right-angle plate, plainly seen in Figs. 3 and 5. The lower inclined part, is, of the plate below the bend, 7', has an oblong hole, 1, into which the end of the tube, A, enters, the bend, j, being 011 top of the tube and the upper inclined part, is, above the said bend serves as a brace to sustain the upright flat plate, D, and resist the tendency of the upper part of that plate to be bent forward by the pull of the woven-wire mattress, m. The upright flat plate, D, has an integral device which engages with the tube, A, when the latter is in the hole, Z, in suitable manner to prevent the said tube from turning in the hole.

The particular construction of this device, or means integrally attached to the plate, for preventing the tube from turning may vary; several forms of construction have been devised by us.

In the present instance the means to accomplish the result of preventing the tube from turning comprises a bar or tang, a, formed on the plate, D, by a suitable die, which produces two parallel slits in the plate, D, and the narrow bar or tang, a, between the slits is pressed forward as shown, and forms a bow which projects beyond the flat surface of said plate. The end of the tube, A, has a notch, 0, which takes over or engages with the said bowed tang, n, as seen in Figs. 2 and 3. It will be seen that the means here described holds the tube, A, and riser rigid and prevents the tube from turning in the hole, Z, of the riser.

The cross-bar, B, has two right-angled sides one of which rests upon the top of the upright flat plate, D, and the other depends down on the back of the said plate where it is secured by bolts, 1), through holes, F, in the top of the riser.-

It will be understood the tube, A, snugly fills the hole, Z, and the extreme end of the tube abuts against the upright plate, D, and the tang device, n, engages the notch, 0, on the tube. The pull of the wire mattress, m, and the described construction keeps the parts connected without bolts or other fastenmgs.

It will be understood by reference to Fig. 3,

IIO

that the strain and pull of the wire-mattress, m, on the top part of the upright plate, D, in the direction shown by the dart, will be effectually resisted by the diagonal position of the lower part, is, of the brace through which the tube, A, extends; and this con struction obviates the necessity of bolts.

That part of the upright plate, D, of the riser which has the bottom flange, e, constitutes the laterally-projecting prong which rests on the side rail, F, near the post of the bed-stead, as shown.

We have pointed out that a feature of novelty and utility is in making the complete riser of a single piece of sheet-metal, namely the broad upright flat plate, D, having the narrower angle-shaped brace, G, extending from its lower edge and thereat united by a band, g, and thence extending upward and having midway of its vertical ends a bend, j, thus forming an upper incline, F, and a lower incline, 7c, the latter being provided with a hole for receiving the end of the stretcher bar, A. We regard our invention, however, as broad enough to cover a riser of this character though made of several pieces.

Having thus described our invention what we claim as new and desire to secure by Letters Patent is,

1. A sheet-metal riser for the support of woven-wire mattresses comprising an upright plate, D, and an angle-shaped brace attached to the side of the said upright platesaid brace having a horizontal bend intermediate of its vertical ends, said bend forming two inclines and the inclined part below the said bend provided with a hole adapted to receive the end of a stretcher tube, as set forth.

2. The combination of a woven-wire mattress; the usual stretcher tubes one at each side-edge of said mattress; and a sheet-metal riser having an upright plate which supports one corner of the mattress a brace attached to one side of said upright plate and having an upper and lower inclinethe latter incline provided with a hole which receives the end of one of said stretcher tubes, and be tween the two inclines a bend which has position on top of said stretcher tube, whereby the necessity of a bolt or other fastener to couple the riser with the said tube is obviated.

3. A sheet-metal riser for the support of woven-wire mattresses comprising an upright plate, D, and an angle-shaped brace attached to the side of the said upright plate said brace having a horizontal bend intermediate of its vertical ends, said bend forming two inclines and the inclined part below the said bend provided with a hole adapted to receive one end of a stretcher tube and means integral with the riser for engaging the tube to prevent the tube from turning when in said hole, as set forth.

In testimony whereof we affix our signatures in presence of two witnesses.
